The SiTime SiT3701 is the smallest programmable voltage-controlled MEMS oscillator (VCMO) on the market today. It features industry-leading 0.5% linear pull range, enabling simpler clock synchronization algorithms, faster system lock time and better stability in clock synchronization and recovery applications. The SiT3701 gives system designers more flexibility with its unique programmable pull range (±30 to ±240 PPM) in a single device – a feature not available in traditional quartz VCXOs.

With its innovative MEMS First™ resonator technology that is replacing decades-old quartz oscillators (XO), SiTime is able to mass produce reliable, high performance silicon timing solutions for a wide variety of applications. The SiT3701 all-silicon VCMO comes in four 4-pin packages with the smallest being 2.5 x 2.0 mm. Like all SiTime products, the SiT3701 programmable VCMO is lead free and RoHS compliant.

Key Features and Benefits

• 0.5% linear pull range simplifies clock synchronization algorithm design and improves system lock time and overall stability
• Fixed control voltage (0 V to 1.75 V) is free from fluctuation in operating voltage and ensures easier migration to system designs using different supply voltage
• Smallest 4-pin package (2.5 x 2.0 mm) enables space saving designs
• Extensive programmability allows designers to use the same base product for many designs, minimizing qualification efforts and consolidating their supplier base
• Any frequency between 1 MHz to 80 MHz
• Selected frequencies between 80 MHz and 110 MHz
• Voltage options of 1.8 V, 2.5 V, 2.8 V and 3.3 V
• Frequency tolerance from ±25 PPM to ±100 PPM
• Pull range of ±30 PPM, ±60 PPM, ±120 PPM and ±240 PPM
• Ultra fast lead time of 2 to 3 weeks enhances our customers’ ability to meet demand fluctuations and reduce inventory overhead
